Evaluation of facial pleasantness in patients with complete and unilateral cleft lip and palate rehabilitated and submitted to orofacial harmonization

ABSTRACT Objective: The objective of the present prospective case control study was to evaluate the facial pleasantness of patients with complete and unilateral cleft lip and palate at the end of interdisciplinary rehabilitation, submitted to facial fillers based on hyaluronic acid. Methods: The study group consisted of 18 individuals with complete unilateral cleft lip and palate, aged between 18 and 40 years (mean age 29 years) of both sexes. The patients presented a concave profile with mild to moderate maxillary deficiency, with completed orthodontic treatment and conducted by means of dentoalveolar compensations without orthognathic surgery. Participants underwent facial filling procedures with hyaluronic acid (HA) in the midface, inserted by a single operator. Standard photographs in frontal norm at rest, right profile at rest, and left profile at rest were obtained from each patient at the following operative times: (T1) pre-filler and (T2) and one-month post-filler. The photographs in T1 and T2 were randomly placed on a page of a virtual album. A 5-point Likert scale was used to assess facial pleasantness. The photographs were evaluated by two groups of evaluators consisting of 18 individuals with cleft lip and palate (CLPG=18) and 18 orthodontists with experience in the treatment of clefts (OG=18). For comparison between phases T1 and T2, and between evaluators with orofacial clefts and orthodontists, the Wilcoxon test was used (p<0,05). Results: People with cleft lip and palate rated their face as more pleasant after the midface filling procedure. In the perception of the orthodontists, on the other hand, the facial pleasantness remained similar after the facial filling procedure. Conclusions: The filling of the middle third of the face in patients with cleft lip and palate treated without orthognathic surgery increased the pleasantness of the face in the opinion of laypeople with cleft lip and palate.

RESUMO Objetivo: O objetivo do presente estudo caso-controle prospectivo foi avaliar a agradabilidade facial de pacientes com fissura labiopalatina completa e unilateral ao final da reabilitação interdisciplinar, submetidos a preenchimentos faciais à base de ácido hialurônico. Métodos: O grupo de estudo foi composto por 18 indivíduos com fissura labiopalatina unilateral completa, com idade entre 18 e 40 anos (média de 29 anos), de ambos os sexos. Os pacientes apresentavam perfil côncavo com deficiência maxilar leve a moderada, com tratamento ortodôntico concluído e realizado por meio de compensações dentoalveolares sem cirurgia ortognática. Os participantes foram submetidos a procedimentos de preenchimento facial com ácido hialurônico (AH) no terço médio da face, implantado por um único operador. Fotografias padrão em norma frontal em repouso, perfil direito em repouso e perfil esquerdo em repouso foram obtidas de cada paciente nos seguintes tempos operatórios: (T1) pré-preenchimento e (T2) um mês pós-preenchimento. As fotografias em T1 e T2 foram inseridas aleatoriamente em uma página de um álbum virtual. Uma escala Likert de 5 pontos foi utilizada para avaliar a agradabilidade facial. As fotografias foram avaliadas por dois grupos de avaliadores formados por 18 indivíduos com fissura labiopalatina (GFLP=18) e 18 ortodontistas com experiência no tratamento de fissuras (GO=18). Para comparação entre as fases T1 e T2, e entre avaliadores com fissura labiopalatina e ortodontistas, foi utilizado o teste de Wilcoxon (p<0,05). Resultados: As pessoas com fissura labiopalatina avaliaram seu rosto como mais agradável após o preenchimento do terço médio da face. Já na percepção do ortodontista, a agradabilidade facial permaneceu semelhante após o procedimento de preenchimento facial. Conclusões: O preenchimento do terço médio da face em pacientes com fissura labiopalatina tratados sem cirurgia ortognática aumentou a agradabilidade da face na opinião dos leigos com fissura labiopalatina.

3D finite element analysis of the influence of upper lip pressure on the maxilla for patients with unilateral alveolar cleft / 口腔疾病防治

Objective @#To investigate the biomechanical effects of upper lip pressure on the maxilla in patients with a unilateral alveolar cleft and provide evidence for clinical diagnosis and treatment. @*Methods @#A 3D finite element maxillary model was generated based on cone beam CT (CBCT) data from an 11-year-old female patient with a unilateral alveolar cleft. Two different kinds of upper lip pressure, postsurgery pressure and normal pressure, were applied to the model. The displacement and stress of each reference node were compared and analyzed. @*Results @# By loading upper lip pressure, the maxillary alveolar crest rotated toward the defect and was displaced downward and backward. The displacement of the noncleft side was greater than that of the cleft side and it decreased gradually from the anterior to the posterior. The stress was concentrated on the anterior portion of the alveolar crest. The stress on the noncleft side was greater than that on the cleft side and it decreased gradually from the anterior to the posterior. The maximum stress was concentrated on the palate around the defect. The displacement and stress in the postsurgery group were greater than those of the normal group (P<0.05). @*Conclusion @#By loading upper lip pressure, the maxilla demonstrated asymmetry three-dimensionally. The adverse effects on the maxilla could be mitigated by reducing the upper lip pressure.

Differences of temporomandibular joint symmetry in patients with unilateral complete cleft lip and palate at different developmental stages / 中南大学学报(医学版)

OBJECTIVES@#Currently, the research results regarding the bilateral temporomandibular joint symmetry in patients at different ages with unilateral complete cleft lip and palate (UCLP) are still controversial. In this study, the position of condyle in the articular fossa and morphology of condyle in UCLP patients at different developmental stages was measured and analyzed to explore the asymmetry difference, which can provide a new theoretical basis for the sequential therapy.@*METHODS@#A total of 90 patients with UCLP were divided into a mixed dentition group (31 cases), a young permanent dentition group (31 cases) and an old permanent dentition group (28 cases) according to age and dentition development. Cone beam computed tomography (CBCT) images were imported into Invivo5 software for 3D reconstruction, and the joint space, anteroposterior diameter, medio-lateral diameter, and height of condylar were measured, and its asymmetry index was calculated.@*RESULTS@#The asymmetry index of condylar height and anteroposterior diameter among the 3 groups, from small to large, was the mixed dentition group<the young permanent dentition group<the old permanent dentition group (both P<0.05). There was no significant difference in condylar anteroposterior diameter and asymmetry index between the mixed dentition group and the young permanent dentition group (both P>0.05), all of them were lower than those in the old permanent dentition group (both P<0.05). Compared with the normal side, the height of fracture condyle was smaller among the 3 groups (all P<0.05), and the anterior joint space was smaller (P<0.05) and the posterior joint space was larger (P<0.05) in the mixed dentition group.@*CONCLUSIONS@#In patients with UCLP, the asymmetry of condylar morphology increases with age, but the condylar position tends to normal. These results suggest that early treatment has important clinical significance for the morphologic development of temporomandibular joint in UCLP patients.

Study on brain mechanism of rehabilitation training of articulation disorder in cleft lip and palate patients based on functional magnetic resonance imaging / 生物医学工程学杂志

The cleft lip and palate (CLP) is one of the most common craniofacial malformations in humans. We collected functional magnetic resonance data of 23 CLP patients before rehabilitation training (Bclp) and 23 CLP patients after rehabilitation training (Aclp), who were performing Chinese character pronunciation tasks, and performed brain activation analysis to explore the changes of brain mechanism in CLP patients after articulation disorder rehabilitation training. The study found that Aclp group had significant activation in the motor cortex, Broca area, Wernicke area and cerebellum. While the Bclp group had weak activation in the motor cortex with a small activation range. By comparing the differences and co-activated brain regions between the two groups, we found that rehabilitation training increased the activity level of negatively activated brain areas (cerebellum, left motor area, Wernicke area, etc.) to a positive level. At the same time, the activity level of weakly activated brain areas (right motor area, Broca area, etc.) was also increased. Rehabilitation training promoted the activity level of articulation-related brain regions. So that the activation intensity of articulation-related brain regions can be used as a quantifiable objective evaluation index to evaluate the effect of rehabilitation training, which is of great significance for the formulation of rehabilitation training programs.

Neste sentido, o objetivo deste estudo é expor as principais dificuldades quanto ao processo de amamentação, trazendo referências atualizadas sobre o tema vinculado ao conhecimento científico. Para tal, realizou-se uma revisão integrativa de literatura com busca de artigos originais e revisões indexadas na base de dados da Biblioteca Virtual em Saúde (BVS), disponíveis pela seleção das plataformas LILACS, BDENF e MEDLINE, adotando critérios de inclusão e exclusão de artigos. Dentre os achados, 70% deles foram de origem internacional, e demonstram que, os lactantes encontram dificuldades para a amamentação conforme o grau da fissura labiopalatina, quanto maior a complexidade da fenda, menor a chance de se realizar o Aleitamento Materno Exclusivo (AME) e as principais dificuldades encontradas foram: desnutrição, perda de peso, sucção débil, pega inadequada da mama e deglutição prejudicada. Destaca-se, também, que, na maioria dos estudos abordados, as mães apresentam dificuldades frente ao diagnóstico não esperado. Portanto, torna-se indispensável aos profissionais da equipe de enfermagem ter o conhecimento científico e preparo assistencial para propor a família dos lactantes formas viáveis para a amamentação.

From the congenital malformation occurring in the 4th week to the 12th week of uterine life, with multifactorial etiology, cleft lip and palate consists of affected facial processes with irregularities which, depending on the complexity of the opening will cause difficulties for breastfeeding infants. In this sense, the objective of this study is to expose the main difficulties regarding the process of breastfeeding, bringing updated references on the subject linked to scientific knowledge. To this end, an integrative literature review was carried out searching for original articles and reviews indexed in the Virtual Health Library (VHL) database, available through the selection of LILACS, BDENF, and MEDLINE platforms, adopting article inclusion and exclusion criteria. Among the findings, 70% were of international origin, and showed that the lactating infants encounter difficulties in breastfeeding according to the degree of cleft lip and palate; the greater the complexity of the cleft, the lower the chance of exclusive breastfeeding (EBF), and the main difficulties found were malnutrition, weight loss, weak suction, inadequate grip on the breast, and impaired deglutition. It is also noteworthy that, in most of the studies approached, mothers have difficulties when facing an unexpected diagnosis. Therefore, it is essential for nursing professionals to have the scientific knowledge and assistance preparation to propose viable forms of breastfeeding to the infants' families.

Closure of maxillary lateral incisor agenesis space in unilateral cleft lip and palate: a digital model assessment

ABSTRACT Objective: To compare dental positional and gingival parameters of maxillary anterior teeth in unilateral cleft lip and palate (UCLP) after orthodontic treatment with canine substitution due to lateral incisor agenesis. Methods: This split-mouth study comprised 57 subjects with UCLP (31 male, 26 female) and agenesis of maxillary lateral incisor at the cleft side, from a single center. Canine substitution was completed after the secondary alveolar bone graft. Dental models were taken between 2 to 6 months after debonding (mean age: 20.4 years). The following variables were measured in the maxillary anterior teeth: crown height, width, proportion, and symmetry, as well as steps between incisal edges, gingival margins, tooth mesiodistal angulation and labiolingual inclination. Paired t-tests with Bonferroni post-hoc correction was used for comparisons between cleft and non-cleft sides (p<0.05). Results: At the cleft side, canines replacing missing lateral incisors had a higher crown height (0.77mm) and an increased width (0.67mm), and first premolars showed a shorter crown height (1.39mm). Asymmetries were observed in the gingival level of central and lateral incisors, with a greater clinical crown at the cleft side (0.61 and 0.81mm, respectively). Cleft side central incisors were more upright than their contralaterals (2.12º). Conclusions: Maxillary anterior teeth demonstrated positional, size and gingival height differences between cleft and non-cleft side after space closure of maxillary lateral incisor agenesis. Slight asymmetries in tooth position and gingival margin in the maxillary anterior teeth should be expected after orthodontic treatment in UCLP patients.

RESUMO Objetivo: O presente trabalho teve como objetivo comparar parâmetros dentários posicionais e gengivais de dentes anteriores superiores em pacientes com fissura labiopalatina transforame unilateral (FLPTU) após tratamento ortodôntico com substituição de incisivo lateral ausente por canino, devido a agenesia. Métodos: Esse estudo de boca dividida reuniu uma amostra, de um mesmo centro especializado de tratamento, de 57 indivíduos com FLPTU (31 homens, 26 mulheres) e agenesia do incisivo lateral superior no lado da fissura. A substituição do incisivo lateral por um canino foi concluída após o enxerto ósseo alveolar secundário. Os modelos dentários foram obtidos entre dois e seis meses após a remoção do aparelho (idade média: 20,4 anos). Foram mensuradas nos dentes anteriores as variáveis: altura, largura, proporção e simetria da coroa, bem como as distâncias entre as bordas incisais, margens gengivais, angulação mesiodistal e inclinação vestibulolingual. O teste t pareado com correção post-hoc de Bonferroni foi usado para comparações entre os lados fissurados e não fissurados (p<0,05). Resultados: No lado fissurado, os caninos que substituíram os incisivos laterais ausentes apresentaram uma altura de coroa maior (0,77 mm) e uma largura aumentada (0,67 mm). Os primeiros pré-molares apresentaram uma altura de coroa menor (1,39 mm). Assimetrias foram observadas no nível gengival dos incisivos centrais e laterais, com maior coroa clínica no lado fissurado (0,61 e 0,81mm, respectivamente). Os incisivos centrais do lado fissurado estavam mais intruídos do que os contralaterais (2,12 mm). Conclusão: Os dentes anteriores superiores demonstraram diferenças de posição, tamanho e altura gengival entre os lados fissurado e não fissurado, após o fechamento do espaço da agenesia dos incisivos laterais superiores. Leves assimetrias na posição do dente e margem gengival nos dentes anteriores superiores devem ser esperadas após o tratamento ortodôntico em pacientes com fissura labiopalatina transforame unilateral.

Caracterización de pacientes con fisura labiopalatina

Introducción: Las fisuras labiopalatinas son los defectos congénitos más frecuentemente atendidas en los servicios de cirugía maxilofacial pediátricos. Estas aparecen precozmente en la vida intrauterina durante el período embrionario e inicio del período fetal. Objetivo: Examinar las características clínicas de pacientes con fisuras labiopalatinas. Métodos: Estudio descriptivo, retrospectivo y transversal. El universo de estudio quedó conformado por 91 historias clínicas de pacientes atendidos en el departamento de Cirugía Maxilofacial del Hospital Pediátrico Universitario "William Soler Ledea" en La Habana, entre 2015 y 2019. Las variables medidas fueron edad, sexo, tipo de fisura, defectos congénitos aislados y defectos congénitos múltiples. Resultados: Predominaron las féminas con 57,1 % y las edades menores de un año para el 54,9 %. Las fisuras palatinas aisladas se presentaron con mayor frecuencia (39,6 %) y las fisuras labiales del lado izquierdo se mostraron en 18 pacientes (32,7 %). El defecto congénito aislado más usual resultó la comunicación interventricular (4,4 %) y el defecto congénito múltiple resultó el síndrome de Goldenhar (5,5 %). Conclusiones: En los niños estudiados con fisuras labiopalatinas existió predominio del sexo femenino, fundamentalmente, en las niñas con menos de cinco años. La fisura palatina aislada resultó la más frecuente; un pequeño grupo de pacientes presentó defectos congénitos asociados, sobre todo cardiovasculares; y los defectos congénitos múltiples se vincularon con mayor frecuencia con las fisuras palatinas aisladas.

Introduction: Cleft lip and palate are the most frequently seen congenital defects in pediatric maxillofacial surgery services. They appear early in intrauterine life during the embryonic and early fetal period. Objective: To examine the clinical characteristics of patients with cleft lip and palate. Methods: Descriptive, retrospective and cross-sectional study. The study universe consisted of 91 clinical histories of patients attended at the Maxillofacial Surgery Department of "William Soler Ledea" University Pediatric Hospital in Havana, between 2015 and 2019. The variables measured were age, sex, type of cleft, isolated congenital defects and multiple congenital defects. Results: Females predominated with 57.1% and ages younger than one year (54.9%). Isolated cleft palates were more frequent (39.6%) and left-sided lip clefts were present in 18 patients (32.7%). The most usual isolated congenital defect was ventricular septal defect (4.4 %) and multiple congenital defect resulted in Goldenhar syndrome (5.5%). Conclusions: In the children studied with cleft lip and palate there was a predominance of the female sex, mainly in girls under five years of age. Isolated cleft palate was the most frequent; and small group of patients presented cleft palate defects.

Evaluation of measuring vomer-palate diameters at 11-13 + 6 weeks of gestation and its diagnostic value for cleft lip and palate / 中华超声影像学杂志

Objective:To investigate the reference range of the length and thickness of the fetal vomer-palate diameters at 11-13 + 6 weeks, and their role in the diagnosis of cleft lip and palate(CLP). Methods:From May 2020 to August 2021, 1 559 pregnant women who underwent ultrasound examination at 11-13 + 6 weeks in Guangdong Women and Children Hospital were selected, and the fetal vomer-palate in the median sagittal plane of the face was observed. The length and thickness diameters of the fetal were measured separately to establish the reference value range of normal fetal.The reference range was compared with the vomer-palate data of fetuses with confirmed CLP. Results:The 1 518 normal fetuses were divided into 11-13 + 6 weeks, 12-12 + 6 weeks and 13-13 + 6 weeks. The reference values of the long diameter of fetal vomer-palatine were 4.3-5.9 mm, 5.0-6.8 mm, 5.4-7.7 mm, and the reference values of the thick diameter were 2.0-2.9 mm, 2.2-3.4 mm, and 2.5-3.8 mm, respectively. The length and thickness of the fetal vomer-palatine were significantly positively correlated with the Crown-rump length ( rs=0.733, 0.634; all P<0.001). In the 1 559 fetals, 25 cases were diagnosed and confirmed with CLP, and the vomer-palate thickness diameters were smaller than the reference values in all cases, meanwhile, the vomer-palate length diameters of 22(88.0)% cases were smaller than the reference values. Conclusions:The reference range of fetal vomer-palate length and thickness at 11-13 + 6 weeks of gestation is valuable for the screening of fetal CLP.

Research progress on early speech interventions for children with cleft lip and palate / 口腔疾病防治

@#Children born with cleft lip and palate (CLP) are at high risk of disorders involving early speech production, and these problems can persist into later childhood, leading to the emergence of compensatory articulation errors. These difficulties in early vocalization directly impact the subsequent development of children's speech and vocabulary. Studies have shown that providing naturalistic interventions, such as milieu teaching and focused stimulation, for children with CLP in the first three years of life have positive impacts on the speech development of children, such as the potential to increase phonemic inventories and the percentage of correct consonants. In addition to speech and language therapists who perform systematic speech therapy, parents can be trained and supervised to deliver early speech intervention. The percentage of correct consonants can be used to assess outcome measures of speech intervention when combined with other measures, such as consonant inventory and speech intelligibility. However, much recent research in the field has focused on older children. Therefore, it must be determined if intervening during the early phase of typical speech development leads to better results. Future research should use more robust methodological designs to determine whether early speech intervention exhibits a positive impact on the speech and future physical and mental development of children with CLP.

Rinoplastia secundaria en pacientes con fisura labiopalatina / Secondary Rhinoplasty in Patients with Clef lip and Palate

Introducción: La deformidad nasal asociada con el labio leporino ha sido vista como uno de los problemas reconstructivos más desafiantes en la rinoplastia, hasta el momento no se ha acordado ningún método único para cuantificar el éxito del tratamiento. En el año 2006 se aprobó oficialmente el protocolo para el tratamiento de las deformidades nasales complejas del Hospital Clínico Quirúrgico "Hermanos Ameijeiras", que están incluidas, las deformidades nasales congénitas secundarias en el adulto, no se recogen antecedentes de resultados en este grupo de pacientes basados en mediciones objetivas. Objetivo: Evaluar los resultados estéticos de la rinoplastia secundaria en pacientes con fisura labiopalatina. Métodos: Se realizó un estudio analítico a través de mediciones nasales angulares y de áreas, comparadas en fotografías estandarizadas entre el pre y posoperatorio y se determinó el índice de asimetría según la fórmula de Nakamura. Un panel de expertos usó la escala de Asher McDade y realizó la evaluación subjetiva de las imágenes, que permitió calcular el índice estético antes y después del tratamiento. Resultados: Se obtuvo una reducción marcada de todos los índices de asimetría nasal entre el pre y posoperatorio, así como una mejoría del índice estético posoperatorio pasándose de una apariencia pobre a muy buena apariencia. Conclusiones: Con la aplicación del protocolo para el tratamiento de las deformidades nasales del paciente fisurado adulto del Hospital Clínico Quirúrgico "Hermanos Ameijeiras" se obtienen buenos resultados estéticos(AU)

Introduction: Nasal deformity associated with cleft lip has been seen as one of the most challenging reconstructive problems in rhinoplasty; up to date, no single method has been agreed upon to quantify management success. In 2006, the protocol for managing complex nasal deformities was officially approved by Hermanos Ameijeiras Clinical Surgical Hospital, which includes secondary congenital nasal deformities in adults; however, there is no history of outcomes in this group of patients based on objective measurements. Objective: To assess the aesthetic outcomes of secondary rhinoplasty in patients with cleft lip and palate. Methods: An analytical study was carried out through linear and angular nasal measurements, compared in standardized photographs between the pre- and postoperative period; while the asymmetry index was determined according to Nakamura's formula. A panel of experts used the Asher McDade scale and performed the subjective assessment of the images, which allowed calculation of the esthetic index before and after the procedure. Results: A marked reduction was obtained in all nasal asymmetry indexes between the pre- and postoperative periods; as well as an improvement in the postoperative aesthetic index, from a poor appearance to a very good appearance. Conclusions: With the application of the protocol for managing nasal deformities of the adult cleft patient of Hermanos Ameijeiras Clinical Surgical Hospital, good esthetic outcomes are obtained(AU)

Esthetic management of a patient with cleft lip and palate

Esthetic rehabilitation of cleft lip and palate patients presents a myriad of challenges and requires interdisciplinary coordination. In the present case report, a 22-year-old male patient with a cleft palate and alveolus was treated. Comprehensive multidisciplinary treatment planning and management, along with a clinician-friendly process of smile designing and of creating mock-ups using digital technology, helped overcome the esthetic challenges faced in this case.

Supernumerary teeth in patients with cleft lip and palate: the tooth germs do not separate

ABSTRACT Introduction: Supernumerary teeth in cases of cleft lip and palate do not result from the division of normal germs before the formation of hard tissue. Deciduous and permanent teeth odontogenesis begins after the face has formed, either with or without the cleft. Discussion: The most acceptable hypothesis to enable understanding of the presence of supernumerary teeth on one or both sides of the cleft palate is hyperactivity of the dental lamina in its walls. This hyperactivity, with the formation of more tooth germs, must be attributed to mediators and genes related to tooth formation, under strong influence of local epigenetic factors, whose developmental environment was affected by the presence of the cleft. Conclusion: The current concepts of embryology no longer support the fusion of embryonic processes for the formation of the face, but rather the leveling of the grooves between them. All human teeth have a dual embryonic origin, as they are composed of ectoderm and mesenchyme/ectomesenchyme, but this does not make it easy for them to be duplicated to form supernumerary teeth.

RESUMO Introdução: Os dentes extranumerários nas fissuras labiopalatinas não são resultado da divisão dos germes normais antes da formação do tecido duro. A odontogênese dos decíduos e permanentes inicia-se depois de formada a face, com ou sem fissuras. Discussão: A hipótese mais plausível para compreender a presença dos dentes extranumerários em um ou nos dois lados da fissura labiopalatina é a hiperatividade da lâmina dentária em suas paredes. Essa hiperatividade, com formação de mais germes dentários, deve ser atribuída aos mediadores e genes relacionados à formação dos dentes, sob forte influência de fatores epigenéticos locais, cujo ambiente de desenvolvimento foi afetado pela presença da fissura. Conclusão: Os conceitos atuais da embriologia não fundamentam mais a fusão de processos embrionários para a formação da face, e sim o nivelamento dos sulcos entre eles. Todos os dentes humanos têm uma dupla origem embrionária, pois se compõem de ectoderma e mesênquima/ectomesênquima, mas isso não facilita sua duplicação para formar dentes extranumerários.

Ultrasonographic diagnosis of fetal cleft lip and palate during first-trimester (11-13 + 6 gestational weeks) / 中华超声影像学杂志

Objective:To explore the clinical value of prenatal ultrasound in diagnosis of fetal cleft lip and palate during first-trimester (11-13 + 6 gestational weeks). Methods:Ultrasonographic images were retrospectively selected from those fetuses who underwent first trimester scanning during July 2017 to June 2020 in the Affiliated Suzhou Hospital of Nanjing Medical University. Fetal facial mid-sagittal section and the retronasal triangle (RNT) section were combined together to evaluate whether the fetuses had cleft lip and palate (CLP) or not. All fetuses were followed up to birth or induced abortion.Results:A total of 5 520 fetuses were enrolled, with crown-rump length (CRL) between 45-84 mm. Seven cases of different types of CLP were detected by the 2 combined sections, including 4 cases with unilateral CLP, 1 case with median CLP, and 2 cases with bilateral CLP, which were confirmed by follow-up. In addition, 2 cases of isolated cleft lip (CL) were missed.Conclusions:Combination of fetal facial mid-sagittal section and RNT section is useful for the early diagnosis of fetal cleft lip and palate during first-trimester scanning.

Portuguese translation and validation of the YQOL ­ FD (Youth Quality of Life Instrument­Facial Differences) for brazilian adolescents with craniofacial deformities / Tradução e validação em português do YQOL - FD (Youth Quality of Life Instrument ­ Facial Differences) para adolescentes brasileiros com deformidades craniofaciais

The Youth Quality of Life­Facial Differences (YQOL-FD), validated in the United States in 2005, was developed at the University of Washington by the Seattle Quality of Life Group (SeaQol), to evaluate quality of life of adolescents with facial deformities. Because no Portuguese version exists, the measure was not viable in Brazil. This study aimed to obtain linguistic and psychometric validation of a version of the YQOL-FD in Portuguese. Twenty-five patients with cleft lip and palate and five without facial deformity participated in Traumatology and Maxillofacial Prosthesis Surgery Clinic, School of Dentistry, University of São Paulo. The linguistic validation of the YQOL-FD was carried out by a team consisting of the researcher, as project manager, two native Portuguese-speaking consultants fluent in English, and one native English-speaking consultant fluent in Portuguese. After translation and back-translation, a Portuguese version was obtained, which was applied in a pilot test (n = 10); after the final adjustments the Seattle Quality of Life Group approved the official version of the YQOL-FD in Portuguese. To obtain the psychometric validation, we requested the participation of 20 patients with cleft lip and palate who answered the questionnaire twice in a range of 7 to 15 days. The Cronbach's alpha test was applied in the 48-item block, showing a high degree of internal consistency (0.949). The Wilcoxon Signal Post Test was applied to verify if the test and retest values were similar; the general agreement was 4/5 = 80%, indicating high reproducibility. It was concluded that the Portuguese version of the YQOL-FD is adequate for evaluating Quality of Life of Brazilian adolescents with craniofacial deformities.

O YQOL-FD (Youth Quality of Life ­ Facial Differences) validado nos EUA em 2005, foi desenvolvido na Universidade de Washington, pelo Seattle Qualitity of Life Group (SeaQol), com a finalidade de avaliar a qualidade de vida de adolescentes com deformidades faciais. Por não apresentar uma versão no idioma português o seu uso não poderia ser viabilizado no Brasil. O objetivo deste trabalho foi conseguir a validação linguística e a validação psicométrica de uma versão do YQOL-FD, no idioma português do Brasil. Participaram deste estudo 25 pacientes com Fissura de Lábio e Palato (FLP) e 5 sem qualquer deformidade facial, em atendimento na Clínica do Departamento de Cirurgia Traumatologia e Prótese Maxilofacial da Faculdade de Odontologia da Universidade de São Paulo. A validação linguística do YQOL-FD foi realizada por uma equipe constituída pelo pesquisador, como gerente de projeto, por 2 consultores nativos da língua portuguesa muito fluentes em inglês e por 1 consultor nativo de língua inglesa com fluência em português. Após a tradução e a retrotradução obteve-se uma versão em português, a qual foi aplicada em um teste piloto, com n = 10, sendo 5 adolescentes com FLP e 5 sem FLP, que após os acertos finais permitiu que o SeaQol aprovasse a versão oficial do YQOL ­ FD em português. Para a obtenção da validação psicométrica solicitou-se a participação de 20 pacientes com FLP que responderam ao questionário por 2 vezes em um intervalo de 7 a 15 dias. O teste de Cronbach foi aplicado no bloco de 48 itens mostrando alto grau de consistência interna (0,949). Na aplicação do Teste dos Postos Sinalizados de Wilcoxon, com o intuito de verificar se os valores do teste (t) e do re-teste (rt) são semelhantes, foi possível observar que a concordância geral é de 4/5 = 80%, portanto uma reprodutibilidade elevada. Concluiu-se que o YQOL­FD na versão em português pode ser utilizado como instrumento adequado para a avaliação da Qualidade de Vida dos adolescentes brasileiros com deformidade carniofacial.

Assessment of Change in SOC of Parents Participating in the Treatment of Their Children Having Cleft Lip & Palate Anomalies

Cleft lip and palate (CLCP) is one of the most common birth defects. The birth of a child with a facial cleft is a tragic incident for the family that the child is born in. Not only is the family devastated by the apparent facial deformity, but also worried about several other issues such as care of the child, the treatment options, and the social impact that the cleft will have for the child and for the family. The purpose of the study was to assess the sense of coherence in parents participating in the treatment of their children with CLCP. Methods50 parents of children with CLCP were evaluated and a questionnaire study was carried out at time intervals of T0, T1 and T2. ResultsMost of the parameters were found to be statistically significant (P<0.05). Overall subjective results were found to be non-significant from T0 - T1. In our study, we found that undergoing orthodontic treatment had positive effects on the parents of patients with CLCP. It was observed that it altered the psychological, financial, emotional and social wellbeing of the parents. ConclusionsIt was concluded that orthodontic treatment should be aimed at both physical and psychological rehabilitation of cleft patients.

Abstract Background: Nasal asymmetry is one of the most frequent characteristics of patients with cleft lip and palate. The anthropometric measurement (AM) is an accessible and reliable method that can be used by specialists to evaluate nasal asymmetry in patients with cleft lip and palate. The aim of this study was to evaluate the effectiveness of an educational intervention applied to cleft lip and palate specialists to increase the accuracy of AM in the evaluation of nasal asymmetry. Methods: Quasi-experimental study. Results: In the first phase of the study, five of the 13 AM reported a mean difference (MD) > 1.5 mm, and 12 of the 13 AM showed results greater than 2 SD (standard deviations). In the second phase, the results showed 11 of the 13 AM with MD < 1 mm, and 9 of the 13 AM were less than 2 SD. Conclusions: The intervention carried out with the manual of AMs increased the knowledge of the specialists on the anatomy points and AM that can be used to evaluate the nasal asymmetry in patients with cleft lip and palate. Educational intervention help to increase the agreement between examiners to perform a reliable evaluation of nasal asymmetry in patients with these conditions.

The first-year follow-up of a cleft lip and palate patient treated with nasoalveolar molding (NAM)

Abstract The objectives of pre-surgical orthopedics are to allow surgical repair with minimal tension of the involved tissues and less restriction to the craniofacial growth. The aim of this study was to evaluate the benefits of nasoalveolar model (NAM) as a pre-operative therapy in a patient with bilateral cleft lip and palate followed by labioplasty and palatoplasty. A 15-day-old patient underwent orthopedic treatment with NAM. After pre-operative treatment, retraction of the pre-maxilla was observed with reduction of the fissure. Due to the successful effects of NAM treatment the patient had a one-step surgery for lip correction. Six months later, due to lip pressure the fissure was further decreased. After six months, the patient underwent palatoplasty. Both surgeries contributed to the remaining closure of the fissure, which were reduced by half compared to the end of pre-operative treatment. The uses of NAM as a pre-operative treatment approached the alveolar segments, centralized the pre-maxilla, decreased the cleft palate resulting in a marked improvement of the arch and provide superior surgical results. In addition, it allows the primary repair of the patient's lip with asymmetric bilateral fissure in only one-step surgery; in consequence, it will reduce treatment morbidity and decrease cost of treatment.

Resumo Os objetivos da ortopedia pré-cirúrgica são permitir a correção cirúrgica com mínima tensão dos tecidos envolvidos e menor restrição ao crescimento craniofacial. O objetivo deste estudo foi avaliar os benefícios do modelo nasoalveolar (NAM) como terapia pré-operatória em um paciente com fissura labiopalatina bilateral seguida de labioplastia e palatoplastia. Um paciente de 15 dias de idade foi submetido a tratamento ortopédico com NAM. Após o tratamento pré-operatório, observou-se retração da pré-maxila com redução da fissura. Devido aos efeitos bem-sucedidos do tratamento com NAM, o paciente realizou a cirurgia em um único tempo cirúrgico para correção dos lábios. Seis meses após verificou-se a continuidade da redução da fissura devido à pressão labial. Após dozes meses, o paciente foi submetido à palatoplastia. Ambas as cirurgias contribuíram para o fechamento remanescente da fissura, que foram reduzidas pela metade em comparação com o final do tratamento pré-operatório. O uso do NAM como tratamento pré-operatório proporcionou a aproximação dos segmentos alveolares, centralização da pré-maxila, diminuição da fissura palatina, resultando em melhora acentuada do arco, resultando em procedimentos cirúrgicos mais eficazes. Além disso, permitiu o reparo primário do lábio do paciente com fissura bilateral assimétrica em apenas uma cirurgia; em conseqüência, reduzindo a morbidade do tratamento e diminuição dos custos do tratamento.

A cross sectional study on mothers’ insight of feeding babies with cleft lip and palate in Hyderabad city, Telangana

Background: Feeding infants with cleft lip and palate is one of the most challenging and worrying events in a mother’s life. When the baby fails to thrive, the mother becomes anxious as the effort goes futile which may inhibit maternal bonding with the child leading to other consequences. Hence, our aim was to assess the attitudes of mothers towards feeding their babies with cleft lip and palate.Methods: A cross sectional study was conducted among mothers of children with cleft lip and palate at a cleft center in Hyderabad city. The mothers were interviewed using a self-administered questionnaire on a 3-point Likert scale. The collected data were subjected to statistical analysis using SPSS version 22.Results: A total of 96 mothers participated in the study. Among them a majority of them bottle fed their baby (85%). Escape of milk through nostrils was reported to be the most common problem faced by the child (30%). The attitudes of mothers were categorized into good (29%), moderate (62.5%) and poor (28%). Also there was a significant difference between the educational qualification, household income and clinical diagnosis with the attitude of mothers.Conclusions: In the present study, a majority of them had moderate attitude. Personal and professional care and support are the key factors influencing the mothers’ attitude.

Association between Genetic Polymorphism in Interferon Regulatory Factor 6 (IRF6) & Non-Syndromic Cleft Lip & Palate Cases in Central Indian Population.

Orofacial clefts can transpire either, as part of complex malformation syndromes, or as an isolated entity, also called non-syndromic cleft. Cleft lip with or without cleft palate (CL/P), collectively termed oral clefts, are the second most commonly observed birth defects among newborns after congenital heart defects. We wanted to investigate the association between genetic polymorphism in Interferon Regulatory Factor 6 (IRF6) & non-syndromic cleft lip and palate (CL/P) cases in Central Indian population.METHODSIn this cross-sectional observational study, the sample comprised of Group 1: 66 individuals and 7 affected families with non-syndromic CL/P; and Group 2: 30 normal individuals and 10 normal families. 5 ml blood sample was collected from each individual following proper surgical protocol using disposable syringes, in blood tubes containing EDTA, with proper labelling and coding for further identification. DNA extraction was done by phenol chloroform extraction protocol and amplification was done using Polymerase Chain Reaction (PCR). Genotyping for the IRF6 polymorphism was completed by restriction digestion of PCR products, also called Restriction Fragment Length Polymorphism (RFLP).RESULTSThe correlative comparison between GG and GA polymorphism in IRF6 gene between affected cases and normal patients shows highly significant value. The comparison between GG & GA polymorphism shows that GG polymorphism is significantly higher in affected cases compared to Group 2. While GA polymorphism is significantly low or decreased in non-syndromic CL/P patients when compared to control group.CONCLUSIONSGG polymorphism is more frequently associated with non-syndromic CL/P as compared to GA polymorphism.

Fissuras Labiopalatais Congênitas: uma análise dos comportamentos e enfrentamentos paternos / Congenital Cleft lip and Palate: an analysis of paternal behaviors and confrontations

Introdução: Fissuras labiopalatais são as mais comuns entre as malformações congênitas craniofaciais e, no Brasil, segundo o Ministério da Saúde, há uma incidência estimada de um para cada 650 nascimentos. O diagnóstico inicial de fissuras causa um grande impacto familiar, resultando em um desequilibrio emocional tanto dos familiares quanto da própria criança, revelando, assim, diferentes formas de reações e enfrentamento dos progenitores, dentre as quais se destacam: choque, luto, negação, culpa, esperança, vergonha, rejeição e até aceitação. Objetivos: Avaliar os indicadores de qualidade de vida dos familiares de crianças com fissuras labiopalatais e analisar seus comportamentos e enfrentamentos frente a essa problemática, bem como, seus primeiros sentimentos, reações e planos de cuidados para uma criança com essa anomalia. Método: Foi realizado um estudo transversal retrospectivo, descritivo e analítico com pais de crianças com fissuras labiopalatais que estavam em tratamento para correção de anomalias craniofaciais no Hospital de Reabilitação de Anomalias Craniofaciais (HRAC), em Bauru, a fim de identificar os padrões de comportamento e a qualidade de vida a partir do questionário The World Health Organization Quality of Life ­ Bref (WHOQOL ­ bref), elaborado pela Organização Mundial de Saúde (OMS). Resultados: Foram avaliados 11 pais de crianças com fissuras labiopalatais, sendo que a maioria era do sexo feminino. Os participantes demonstraram diferentes posicionamentos frente à problemática e foram observadas variações de domínios nas respostas do questionário WHOQOL ­ bref, resultando em uma grande modificação no bem estar dos familiares envolvidos. Considerações finais: As famílias passam por uma lenta adaptação com uma criança fissurada, mas apesar das modificações da qualidade de vida, a maioria consegue superar os sentimentos negativos.

Introduction: Cleft lip and palate are the most common among the congenital craniofacial malformations, and, according to the Brazilian Health Ministry, in Brazil, it has an estimated incidence of 1 to every 650 children born. Its initial diagnostic causes a considerable impact on the family and results in an emotional imbalance both in the family and in the children themselves, revealing different ways of reactions and confrontation of the progenitors, which are: chock, mourning, denial, guilt, hope, shame, rejection, and even acceptance. Goals: This study aimed to evaluate the quality of life indicators of the relatives of kids with cleft lip and palate and analyze their behavior and how they face these issues such as their first feelings, reactions, and care plans created for a child with this anomaly. Method: A retrospective, descriptive, and analytical crosssectional study was conducted with the parents of children with cleft lip and palate, who were undergoing treatment for the correction of craniofacial anomalies at the Hospital de Reabilitação de Anomalias Craniofaciais (HRAC) in Bauru to identify patterns of behavior and the quality of life from the questionnaire The World Health Organization Quality of Life ­ Bref (WHOQOL ­ bref), created by the World Health Organization (WHO). Results: Eleven parents of children with cleft lip and palate, mostly female, were evaluated. The participants demonstrated different positions regarding the problem and domain variations observed in the answers to the WHOQOL - bref questionnaire, resulting in a considerable change in the well-being of the family members involved. Final considerations: Families go through a slow adaptation with a fissured child, but despite the alterations in quality of life, most manage to overcome negative feelings.
